Filed: 1981-02-25
Granted: 1984-11-15
Abstract: A process and apparatus for preparing anisotropic metallic and ceramic compositions or material includes floating zone melting of eutectics and orientation of eutectoids, as well as melting, frittering, or homogenization of the eutectoids prior to orientation. The process includes solidification of a eutectic in the presence of a thermal gradient while displacing the solidification front of the eutectic along the direction of the gradient and orienting the solid eutectoid which results by imposing a direction of growth on it by displacement of the composition itself or the temperature gradient. The eutectoids are then prepared in a reactive atmosphere within a container and the surface thereof treated in gaseous atmosphere, after which the materials are compacted by displacing them again. The apparatus for performing the process includes a double heating and cooling system and structure for translating and rotating these systems. It additionally includes a support plate for supporting the elements being oriented, the plate being attached to a displacement shaft. Electronic controls for all of the structures are connected to temperature and displacement sensors.

Granted: 1987-01-15
Abstract: PCT No. PCT/FR81/00132 Sec. 371 Date Jun. 21, 1982 Sec. 102(e) Date Jun. 21, 1982 PCT Filed Oct. 20, 1981 PCT Pub. No. WO82/01405 PCT Pub. Date Apr. 29, 1982.A spring-applied, air-released parking/emergency brake is combined with an air-actuated service brake through a friction clutch between the parking/emergency brake piston and a first nut member that is threaded onto a screw rod of the service piston. The screw rod and service piston are connected through another friction clutch. The screw rod is provided with a second nut member that is integral with a thrust rod to which the brake rigging is connected. A friction lock slack adjuster arrangement limits retraction of the thrust rod during brake release in accordance with the desired brake shoe clearance to be maintained. When the thrust rod movement is inhibited by the slack adjuster, the service piston clutch becomes disengaged to permit rotation of the screw rod during the release stroke of the service piston corresponding to overtravel due to shoe wear. Brake shoe clearance is thus maintained constant. The service piston clutch is engaged during a service application so as to induce rotation of the first nut member, which is accordingly maintained at a given point of axial reference relative to the parking/emergency brake piston, so that the actuating spring force is constant any time the parking/emergency brake is activated.

Granted: 1990-08-23
Abstract: A method of taking measurements of an article during manufacture, or of the finished product, without physically contacting the article wherein a series of scans of the article is made by means of an electronic video camera to produce a video signal which is displayed in a visual display unit (VDU) whilst the article which at the commencement of the process has been precisely located relative a pair of orthogonal datum cordinates (corresponding to "X" and "Z" directions of measurement) in a prescribed plane is advanced in prescribed increments and at corresponding intervals along one of said cordinates (i.e. in the "Z" direction) in the said plane, the article being illuminated along a narrow strip oriented along or parallel to the other said cordinate (i.e. in the "X" direction) from a light source which is angularly displaced from the camera within a plane perpendicular to the first said plane which is parallel to the said "Z" direction. 
<??>The light source which is preferably a laser provides a thin fan-shaped beam. Any areas of the article obstructed from the beam by overhanging portions of the article are illuminated from the same beam by means of reflectors placed at the sides of the articles within the beam. If the same or other areas are likewise shielded from the camera, additional reflectors are placed alongside the article, but within the field of view of the camera, so as to reflect images of these areas into the camera. 
<??>A counter which totalizes the incremental displacements of the article in the "Z direction and which provides a display of the running count during each interval is arranged in a prescribed location within the field of view of the camera. The counter, which is zeroed at the commencement of the process, appears in the video display throughout the process as an indication of displacement of the article in the "Z" direction. 
<??>The video signal respecting the camera scan during each interval is displayed on the VDU alongside a display of a video recording of the corresponding scan of a master representation made under precisely identical conditions, and the amplitudes of the two signals (corresponding to "Y" direction of measurement) relative to common positions along their respective base lines corresponding to "X" directions of measurement) are then accurately compared to indicate the dimensional variations of the article from the master representation. 
<??>A manual tracking means for use with the visual display unit is disclosed by means of which the displays respectively corresponding to the article and the master representation (each of which is seen as a line tracking over the screen of the VDU, both in the same direction) are tracked, the displacements in the "X" and "Y" direction being automatically measured and digitised, and the "Y" displacements being aautomatically compensated to produce true "Y" displacements in the plane perpendicular to the said prescribed plane.
